Answer :

To solve the expression [tex]\(10.1 \times 80\)[/tex], we need to multiply the two numbers given:

1. Identify the Numbers: We have two numbers in the problem, 10.1 and 80.

2. Understand the Operation: The dot and double prime symbols seem to suggest multiplication, so we are multiplying 10.1 by 80.

3. Perform the Multiplication: Multiply 10.1 by 80.
- First, ignore the decimal and calculate [tex]\(101 \times 80\)[/tex].
- [tex]\(101 \times 80 = 8080\)[/tex].
- Then, place the decimal point back in the product. Since 10.1 has one decimal place, the product should also have one decimal place.

Thus, the calculated result is [tex]\(808.0\)[/tex].
